The Criminal Procedure (Identification) Act, 2022 enables Indian law enforcement agencies to collect, store, and analyze physical and biometric data of individuals involved in criminal cases. The Act replaces the Identification of Prisoners Act, 1920. The Act authorizes the collection of data such as fingerprints, iris and retina scans, and physical measurements from convicted individuals and those accused of specific offenses. Aimed at modernizing investigative processes, the Act allows this data to be stored for up to 75 years and used to identify repeat offenders and improve crime-solving efficiency. It also specifies that the National Crime Records Bureau (NCRB) will manage the data collection and storage.
